TO ALL WHOM IT MAY CONCERN:

Be it known that I, DENNIS SAVERY, of Wheeling, in the county of Ohio,and State of West Virginia, have invented a new and useful Improvementin Nail Machines; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being bad to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a top view of my improvement. I

Figure 2 is a side view of the same, with the anvil-block and gripershown in rec, the latter being raised above the nail-block, shown 'inblue lines. I

Similar letters of reference indicate like parts.

The nature of this invention relates to the action of the griping-leveror griper, so called, and operates to retract the griper from contactwith the nail-blankafter the latter has been headed.

It is always desirable'in the operation of nail-machines to have thegriper retracted as speedily'as possible, and various devices have beenused to accomplish this object, bnt'none heretofore have accomplishedthe retracting in as perfect and instantaneous manner as is doneby myinvention. 7

It consists ofa U-shaped spring, one-end of which is aifixed to thecam-end of the griper, and the other clasps or bears against on thatside of the cam-shaft which is opposite the griper, thus holding the endof the griper against the shaft, and byits tension, actuating the griperagainst the shaft instantaneously after the cam has passed thetappet-projection. on the griper.

In the drawings- A is the cam-shaft, B the cam thereon, and G thegriping-lever, having a tappet, a.

D is the U-shaped spring, afiixed to the end of the griping-lever, asshown, and bearing against the opposite side of the shaft A.

A plate, I), is afiixed, by bolts or other suitable means, to theproximate side of the spring at that point,

and the said plate bears a leather or other porous pad to soften theaction of the spring and return the lubricating-material.

E E are the trunnions or vibrating centre of the griper.

As the cam 13 passes the tappet a, the spring retracts the griperinstantaneously, as will be obvious, and at each revolution the cam islubricated by its passage in contact with the pad e, which is saturatedwith the lubricating-material.

In fig. 2 the griper a is shown in red attached to the griping-lever O,and in a raised position above the nail-blank. 7

Having thus described my invention, I claim as new, and desire to secureby Letters Patent The arrangement of the lever C, tappet a, spring I),plate 6, pad e, cam B, and shaft A, in the manner and for the purposespecified. 7
